BOTTLE-SEAl- ING DEVICE.

SPECIFICATION forming part Of Letters Patent N0. 608,157, dated July 26, 1898. Application lcd February 9, 18973. Serial No, 461,607. (No model.)

To CLZZ whom f may concern: t Be it known that I, WILLIAM PAINTEE, of

the city of Baltimore, in the State of Mary of bottle-sealing devices which involve the use of bottles having on their heads an annular locking-shoulder together with sealingdisks which are maintained in sealingcontact with the lips of the bottles by means of hard-metal sealing-caps.

My invention consists in providing flanged hard-metal caps with a series of detachinglugs projected from the and remote from its edge above its point of engagement with the locking-shoulder on the bottle. The lower' surfaces of said lugs afford shoulders with which any suitable bottleopener may reliably engage for detaehing the caps from bottles. These lugs are integrally formed by an Outward displacement of the metal at more or less regular intervals and preferably in such close proximity to each other as will enable a bottle-opener to be applied without reference to any special peripheral location on the cap and also so that several of the lugs may be simultaneously engaged by an opener. VThe portion of the capflange which is made to engage in locking Contact with the bottle is sufficiently thin and ductile to enable it to be closed inwardly against the glass by the application of rolling or spinning pressure.

To more particularly describe my present invention, I will refer to the accompanying drawings, in which- Figure l, in side view, top View, and section, illustrates one of my sealing-caps in a desirable form without its sealing-disk. Fig. 2, in section, illustratesa bottle-head with one of said caps applied thereto with a sealingdisk. Fig. 8, in side vieWand section, illustrates onejof my caps having detaching-lugs differing in form from those shown in Fig. l. The cap A, Fig. l, is composed of suitable flange of each cap' hard metal, preferably tinn ed sheet-iron, and its interiorsurface is shaped so as to conform quite closely to the exterior shape of the lip of the bottle with which it is to be used. The cap-ange, near its edge o, is plain, and the metal is sufficiently thin and soft to enable it to be properly forced into good engaging contact with the locking-shoulder of a bottle. The several detaching-lugs b are located sufficiently remote from the edge a to not interfere with the proper working of the metal in applyingA the cap to a bottle and also sufficiently remote from the top of the cap to not relieve a sealing-disk from desirably uniform compression; but this would be immaterial if the cap was used for confining an ordinary cork in a bottle neck. These lugs b are formed by outwardly displacing the metal in the flange, so as to afford an abrupt shoulder at the lower end of each lug, as at b', and in this instance at said lower end there is an opening into the cap, asp-,indicated in the sectional view of Fig. l, the abrupt shoulder in this case being afforded by the edge of that portion of the metalwhich is outwardly displaced at the base of each lug. The sealingdisk c may be varied in its character, but is preferably a thin cork disk.

The bottle-head B, as shown in Fig. 2, has a rounded lip and an annular locking-shoulder at CZ. The cap A, with its disk c, is placed on the bottle-head and pressure applied to the top of the cap for closely conforming the disk to the lip of the bottle, and then While still under sealing pressure the fiange is rolled into contact with and beneath said shoulder, thus maintaining the disk in proper sealing contact with the lip of the bottle. The union of a hard-metal cap thus applied to a bottle is so firm that a powerful prying action is required, as by the use of any form of bottle-opener which by engaging with such detaching-lugs will operate with leverage in wrenching the cap from the bottle, al though the lugs located -remotelyfrom the edge of the flange, as described, will serve as detaching-lugs, regardless of the manner in which a reliable locking union of the cap and bottle may be effected.

It is not essential that the lower ends of the detachingflugs should be open or that IOO they should be otherwise precisely formed, as shown in Figs. 1 and 2, as, for instance, as shown in Fig. 3, the cap A has pear-shaped detaching-lugs b2, the lower or large ends of which are not open, but the metal is so bent and displaced as to alord a shoulder suflciently abrupt to enable va suitable opener to properly engage therewith.

As compared with a cap having an annular detaching-rib my present cap, having the detaching-lugs, is, when in use, somewhatf less liable to vary in its compressing relations i to a sealing-disk than a cap having an annu- 1 lar rib, because the latter is formed by folding or bending a portionY of the flange upon itself in a line transverse to the line of dis-r placing strain, so that when .under extraordinary heavy gaseous pressure the upper and lower sides of the rib might be slightly parted, so as to correspondingly relieve the disk from compression, whereas with my present caps v the metal between the lugs is not folded, and

hence is incapable of yielding to any outward strains to which the cap can possibly be subjected.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A metallic bottle-sealing cap, having a Y iiange, provided with outwardly-projecting lugs, located remotely from the edge of the cap, substantially as described.

2; The combination of a bottle having on its head an annular locking-shoulder, and a metallic sealing-cap containing a sealing-disk under compression, and having a flange provided with outWardly-projecting detachinglugs, and also having its edge below said lugs, in reliable looking contact with the annular locking-shoulder, substantially as described.
